There are three units of measure in space, km, AU, and Ly. That's kilometers, Astronomical Units, and light years. My personal favorite is light years because its such a very long distance. I mean it only takes eight minutes to travel from earth to the sun at light speed, but that's beside the point. Kilometers is generally used to measure short distances like earth's radius. AU is used for more challenging tasks, such as the distance between planets. Light Year literally means the distance light travels in a year. As light can travel great distances in practically no time at all, thsi is used for such things as the distance between galaxies or universes.
At its nearest point, asteroid Hermes is only 300,000 miles from earth. That's just 482803 km. It's only a little farther than the moon. Unfortunately, it would not be possible to land on Hermes as it is to small and is moving to fast.
